High Precision Event Timer (HPET) is a hardware timer that is used to provide high-resolution timing support for operating systems and applications.
It is designed to replace the older Programmable Interval Timer (PIT) and Advanced Configuration and Power Interface (ACPI) timer, which have lower resolution and are less precise.
HPET is a hardware timer that is implemented using a dedicated hardware circuit on the motherboard.
It is accessed through a special interface in the operating system, which allows applications and the operating system to use it to measure time intervals with a high level of accuracy.
HPET can be used for a wide range of purposes, such as measuring the performance of applications, synchronizing events, and providing timing for multimedia applications.
One of the main advantages of HPET is its high resolution, which allows it to measure time intervals with a much higher degree of accuracy than other hardware timers.
It is also able to operate at a much higher frequency than other timers, which can be useful for applications that require fast and precise timing.
